AT91SAM7S-EK and eCos

Hi,

I’m the beginner eCos user. Now I’m trying to run eCos on the AT91SAM7S-EK. I’ve downloaded newest version of eCos source code and the configtool from cvs. After setup for AT91 I have successfully compiled eCos libs with default compilation options except -g option. I have removed -g option from options to minimize size of kernel.

I wanted to run the “Hello, eCos world!” example, I have compiled those examples using default Makefile from /examples directory. Then I have downloaded result (“examples/hello”) using SAM-BA to the AT91SAM7S-EK board. The board was connected to PC via SERIAL0 and DBGU to PC where I have got 2 hyperterminals (38400 8-n-1 non-flow control).

I’m expecting to observe “Hello, eCos world!” on one of the hyperterminals, but after reset there was no output.

How should I configure or compile the example to run examples?

How should I download compilation result to board?

Is it possible to change arm-serial port for printf function?

Is there any tutorial for eCos on AT91SAM7S-EK?
